Front

What is the sun and its significance in the solar system?

Back

The sun is the star at the center of the solar system, providing light and heat essential for life on Earth.

Front

What is carbon dioxide and its role in respiration?

Back

Carbon dioxide is a gas produced by cells during respiration, which is essential for the process of photosynthesis in plants.

Front

Explain the water cycle.

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, and precipitation.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

Describe the process of respiration in living organisms.

Back

Respiration is the biochemical process in which cells convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, create their own food through photosynthesis and serve as the primary source of energy for other organisms in the ecosystem.

Front

Define the term 'ecosystem'.

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic and abiotic components.
